PORTABLE FIREPLACE.

Specification of Letters Patent.

Patented June 1, 1909.

Application filed January 16, 1909. Serial No. 472,611.

1 State of Massachusetts, have invented new and useful Improvements inPortable Fireplaces, of which the following is a specification.

This invention relates to a portable fire place, the object of theinvention being to provide a fire place which can be placed in anyapartment and connected to the ordinary cylindrical flue by means ofpipe, and yet give to the room the appearance of a fire place built intothe chimney breast, and further the object of this invention is toprovide a fire place which will not only heat the room in which it isplaced by direct radiation, but

will also heat the room by hot air and purify the air taken from theroom by sterilizing the same.

The invention further has for its object to provide hot air inconnection with the direct radiation of heat from the fire place andfire box, which hot air may be carried by suitable pipes to other roomsthan that in which the fire place is located.

The invention consists in a portable fire place such as described in thefollowing specification and particularly as set forth in the claims.

Referring to the drawings: Figure 1 is a front elevation of my improvedfire place and mantel. Fig. 2 is a sectional elevation taken on line 22of Fig. 1. Fig. 3 is a sectional plan taken on line 33 of Fig. 1.

Like characters refer to like parts throughout the several views of thedrawings.

In the drawings, 5 is a fire box consisting of a back plate 6,preferably formed of corrugated iron, two side plates 7, 7, and a bottomplate 8. A grate 9 is preferably attached to the fire box or astep-grate may be used, if desired. A blower 10 is preferably suppliedto regulate the draft on the fire place.

A flue chamber 11 is provided into which the fire box opens at its upperend at 12. Said flue chamber has a top 13, a back 14, a front 15 and abottom 16 and extends entirely across the space between the two sides 7,7 of the fire box, which sides are extended upwardly to the top 13. Inthe back 14 of the flue chamber is a cylindrical opening 17 adapted toreceive a pipe 18, which pipe is adapted to be connected to or insertedin a chimney flue 19.

A hot air chamber 20 extends across the back and sides of the fire box5, said hot air chamber having a back plate 21 and side plates 22, 22,the bottom plate 8 of the fire box being extended to close the bottom ofthe hot air chamber 20. The hot air chamber 20 is divided into two parts20 and 20" by a vertical partition 23, which partition extends from theplate 16 to the plate 8 within the hot air chamber. Each of the hot airchambers 20 and 20 has an inlet opening 24 and an outlet opening 25which may be opened or closed by means of a suitable register, and theair as it passes upwardly through the hot air chambers 20 and 20 isdiverted in its course by means of baffle plates 20", 20.

A cold air supply is obtained from a cold air chamber 26 which extendsacross beneath the bottom of the fire box and has inlet openings 27, 27.These inlet openings are regulated by means of suitable doors or dampers28. Other outlets from the hot air chambers 20 and 20 are provided at 29and 30, respectively, these outlets being cylindrical and adapted tohave a pipe attached. thereto, which pipes can be carried to other roomsthan that in which the fire place itself is located.

A secondary hot air chamber 31 having a back wall 38 extends across theback of the primary hot air chamber 20 and forwardly outside both sidesof said hot air chamber having side walls 32, 32.

A cold air chamber 33 located beneath the hot air chamber 20 and beneaththe fire box 5 supplies fresh air to the secondary hot air chamber 3 1,said cold air chamber having inlet openings 34, 34 through which airfrom the room enters said cold air chamber and being divided from thecold air chamber 26 by a vertical partition 39. Outlet openings 35, 35are provided, preferably near the top of the side portions 32, 32 of thesecondary hot air chamber, and these outlet openings are provided withsuitable registers or dampers to regulate the amount of hot air whichmay pass therethrough.

The portable fire place hereinbefore described is rendered ornamental bya sheet metal structure designed and formed to present the appearance ofa mantel including columns or pilasters 36, 36 and a shelf 37, so thatviewed from the front of the fire place, when the same is in position,said fire place presents the appearance of the ordinary fire place builtinto the breast of a chimney with a mantel surrounding the same, so thatthe device presents an ornamental appearance and is useful as a mantel,in addition to its usefulness as a heating medium or device, and, ashereinbefore set forth, the heat obtained is not only that which isderived from direct radiation from the fuel and the heated fire box, butalso heat is derived from the hot air, so that a constant circulation ofthe air in the room is obtained, and said air, as it circulates throughthe heated chambers of the fire place, becomes sterilized and purilied.

In using my improved fire place the same is set in position with thepipe 18 projecting into the flue 19 and the same is set close againstthe wall, which can be done without danger of fire, on account of thetwo air chambers between the fire and the wall which form non-conductorsof heat. Then the fire place has been thus set in position, it is usedthe same as though the iire place were set permanently in a chimney. Theair enters through the inlet openings 27 into the cold air chamber 26,thence passes through the outlet openings 24 into the hot air chambers20 and 20 and passes upwardly through said chambers, as indicated by thearrows a, and passes outwardly through the outlets or registers 25. Theair for the secondary hot air chamber passes into the cold air chamber33 through the inlets 34, thence said cold air passes upwardly into thehot air chamber 31 and through the side chambers 32, 32 thereof, asindicated by the arrows b, and outwardly through the registers oropenings 35, 35. As the hot air asses upwardly through the hot airchamers 20 and 20 it is deflected from side to side by baffle plates 31,31. 7

Having thus described my invention, what I claim and desire by LettersPatent to se cure is:

1. A portable fire place structure including a fire-box, said structurebeing provided with a primary hot air chamber extending across the backand both sides of said fire-box and provided with outlets leading out ofthe upper portion of said primary hot air chamber, said structure beingprovided with a secondary hot air chamber extending across the back andboth sides of said primary hot air chamber, said structure beingprovided with outlets leading out of the upper portion of said secondaryhot air chamber, said structure being further provided with twoindependent cold air chambers and still further provided with inletflues leading into said cold air chambers and also being provided withoutlet flues opening from one of said cold air chambers into saidprimary hot air chamber and from the other of said cold air ghambersinto said secondary hot air cham- 2. A portable fire place having, incombination, a fire-box adapted to be connected to a chimney flue, wallssurrounding said fire-box and forming together with walls of saidfire-box a primary hot air chamber eX- tending across the back and bothsides of said fire-box, said walls being provided with outlets leadingout of the upper portion of said primary hot air chamber, other wallsforming with walls of said primary hot air chamber a secondary hot airchamber eX- tending across the back and both sides of said primary hotair chamber, said walls provided with outlets leading out of the upperportion of said secondary hot air chamber, and walls forming with thebottom plate of said primary and hot air chambers and firebOX twoindependent cold air chambers beneath said fire-box, said walls havinginlet fiues opening into said cold air chambers and outlet flues openingfrom one of said cold air chambers into said primary hot air chamber andfrom the other of said cold air chambers into said secondary hot airchamber.

In testimony whereof I have hereunto set my hand in presence of twosubscribing wit- IIGSSBS.
